Abstract
AIMS Itch, a common uncomfortable sensory experience, occurs frequently in inflammatory or allergic disorders. In recent years, with the discovery of itch-specific pathways in the peripheral and central nervous system, the association between immunology and neural pathways has gradually emerged as the main mechanism of itch. Although many studies have been conducted on itch, no bibliometric analysis study focusing on this topic has been conducted. This study aimed to explore the research hotspots and trends in the itch field from a bibliometric perspective. METHODS Publications relevant to itch, published from 2003 to 2022, were retrieved from the Science Citation Index-Expanded of Web of Science Core Collection. Publications were critically reviewed and analyzed with CiteSpace software, Vosviewer, and the bibliometric online analysis platform. Visual maps were conducted in terms of annual production, collaborating countries or institutions, productive authors, core journals, co-cited references, and keyword bursts. RESULTS 2395 articles on itch that met our criteria were identified and the quantity of publications has been increasing rapidly since 2012. The USA was the most influential country. University Hospital Münster was the institution with the most publications. Gil Yosipovitch was the most prolific author. Atopic dermatitis (AD), intradermal serotonin, chronic pruritus, mechanical itch, gastrin-releasing peptide, substance p, interleukin-31 receptor, histamine-induced itch, bile acid, scratching behavior, and h-4 receptor were the top 11 clusters in co-citation cluster analysis. Keyword burst analysis suggested that treatment, inflammation, and AD are current research hotspots. CONCLUSION Global publications on itch research have increased steadily and rapidly over the past 20 years. Inflammation and AD are current research hotspots. The neuroimmunological and neuroinflammatory mechanisms of itch, as well as clinical assessment methods and therapeutic targets, will be novel research directions in the future. This study provides guidance for further itch research.

Abstract
In recent years, AMPK channel has gained considerable attention in a variety of research areas, and several academic journals have published articles on AMPK research. However, few attempts have been made to thoroughly assess the scientific output and current status systematically in this topic from a worldwide viewpoint. As a result, it is critical to adopt an appropriate visualization method to reveal the global status, future research trends, and hotspots in AMPK channel research. To investigate research hotspots/frontiers in certain domains, bibliometric analysis has been frequently utilized to determine the productivity of nations, institutions, authors, and the frequency of keywords. In this work, we used CiteSpace and VOSviewer to conduct a bibliometric analysis of AMPK channel studies from 2012 to 2021 in order to perform researchers with some directions for AMPK channel research.

Abstract
The repair of osteochondral defects is among the top ten medical needs of humans in the 21st centuries with many countries facing rapidly aging population involved with osteoarthritis as a major contributor to global disease burden. Tissue engineering methods have offered new windows of hope to treat such disorders and disabilities. Regenerative approaches to cartilage injuries require careful replication of the complex microenvironment of the native tissue. The decellularized hyaline cartilage derived from human allografts or xenografts is potentially an ideal scaffold, simulating the mechanical and biochemical properties, as well as biological microarchitecture of the hyaline cartilage. There have been many attempts to regenerate clinically viable hyaline cartilage tissue using decellularized cartilage-derived extracellular matrix with stem cell technology. This chapter describes the reproducible methods for hyaline cartilage decellularization and recellularization. In addition, quality control and characterization requirements of the product at each step, as well as the clinical applications of final product have been discussed.

Abstract
There are no commercially available effective antiviral medications or vaccines to deal with novel coronavirus disease (COVID-19). Hence there is a substantial unmet medical need for new and efficacious treatment options for COVID-19. Most COVID-19 deaths result from acute respiratory distress syndrome (ARDS). This virus induces excessive and aberrant inflammation so it is important to control the inflammation as soon as possible. To date, results of numerous studies have been shown that mesenchymal stem cells and their derivatives can suppress inflammation. Exosomes function as intercellular communication vehicles to transfer bioactive molecules (based on their origins), between cells. In this review, the recent exosome-based clinical trials for the treatment of COVID-19 are presented. Potential therapy may include the following items: First, using mesenchymal stem cells secretome. Second, incorporating specific miRNAs and mRNAs into exosomes and last, using exosomes as carriers to deliver drugs.

Abstract
BACKGROUND Management of multisegmental tracheal stenosis is challenging. In this 24-year longitudinal single-center study, we present an algorithmic treatment approach. METHODS A retrospective analysis of 2167 patients with postintubation tracheal stenosis indicated 83 (3.83%) patients with multisegmental tracheal stenosis. Patients were assigned to 4 management groups according to the length, location, and severity of stenoses; tracheal infection/mucositis; laryngeal function; symptoms; general condition; and comorbid diseases. Type 1 (n = 13): 1-stage resection of both strictures, Type 2 (n = 6): 2-stage resection of both strictures, Type 3 (n = 40): resection of 1 stricture and nonresectional management of the other, Type 4 (n = 24): nonresectional management of both strictures. Outcomes were categorized as Good, Acceptable, or Poor. Univariate analyses for factors predictive of recurrence and outcome were performed. RESULTS Follow-ups were completed in 70 (84.34%) patients (median, 22.5 months). Outcome was assessed as Good in 56 (82.35%), Acceptable in 10 (14.71%), Poor in 2 (2.94%), and mortality in 2 (2.94%) patients. The median length of airway resection was 46, 67.5, and 40 mm in Types 1-3, respectively. Only 11 (13.25%) patients had no history of tracheostomy or tracheal surgery. By univariate analysis, a shorter intubation period was associated with Good outcome (P = .017). No factors predictive of recurrence or outcome were ascertained. CONCLUSIONS Multisegmental tracheal stenosis, generally caused by performing an inappropriate tracheostomy, is an iatrogenic disease that can be prevented. Although resection of both strictures may be feasible and is associated with Good results, in the majority of cases, a combination of surgical resection and non-resectional methods are sufficient to achieve Good results.

Abstract
Current therapies for novel coronavirus disease (COVID‐19) are generally used to manage rather than cure this highly infective disease. Therefore, there is a significant unmet medical need for a safe and effective treatment for COVID‐19. Inflammation is the driving force behind coronavirus infections, and the majority of deaths caused by COVID‐19 are the result of acute respiratory distress syndrome (ARDS). It is crucial to control the inflammation as early as possible. To date, numerous studies have been conducted to evaluate the safety and efficacy of tissue engineering and regenerative medicine (TERM) products, including mesenchymal stem cells (MSCs), and their derivatives (eg, exosomes) for coronavirus infections, which could be applied for the COVID‐19. In this review, first, the impacts of the COVID‐19 pandemic in the present and future of TERM research and products are briefly presented. Then, the recent clinical trials and the therapeutic benefits of MSCs in coronavirus‐induced ARDS are critically reviewed. Last, recent advances in the field of tissue engineering relevant to coronavirus infections, including three‐dimensional platforms to study the disease progression and test the effects of antiviral agents, are described. Moreover, the application of biomaterials for vaccine technology and drug delivery are highlighted. Despite promising results in the preclinical and clinical applications of MSC therapy for coronavirus infections, controversy still exists, and thus further investigation is required to understand the efficacy of these therapies.

Moradi L, Mohammadi Jobania B, Jafarnezhad-Ansariha F, Ghorbani F, Esmaeil-Pour R, Majidi Zolbina M, Kajbafzadeh AM. Evaluation of different sterilization methods for decellularized kidney tissue. Tissue Cell 2020; 66:101396. [PMID: 32933719 DOI: 10.1016/j.tice.2020.101396] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2020] [Revised: 05/15/2020] [Accepted: 06/01/2020] [Indexed: 12/16/2022]
Abstract
The main goal of this study was to assess the effect of different sterilization treatment for sterilization of decellularized kidney tissue. Rabbit kidneys were decellularized by the perfusion-based method using sodium dodecyl sulfate (SDS) and Triton X-100. Then, decellularized kidney slices were prepared and sterilized by an antibiotic cocktail, PAA (0.5 %, 1% and 1.5 %), 5KG γ-irradiation and 320-480 nm UV-irradiation. Histological evaluations, DNA quantification assay, MTT assay, scanning electron microscopy (SEM), mechanical test and bacterial and fungal culture tests were performed to determine the quality of decellularization and sterilization processes. The kidney slices were seeded by adipose-derived mesenchymal stem cells (ASCs) to assess the cell adhesion capability after treatment. The results of the current study indicated that PAA 0.5 % was the most efficient method to completely decontaminate rabbit decellularized kidney tissue while preserving the mechanical properties and main components of the matrix which are necessary for cell-matrix interaction and cell adhesion. The 5KG γ-irradiation was determined to be the most destructive sterilization method, with reduced the mechanical strengths as well as altered microstructure of the kidney matrix and no cell adhesion. In addition, UV-irradiation is not able to sterile the decellularized tissues. Therefore PAA 0.5 % sterilization method can be a powerful means for sterilization of biological scaffolds.

Abstract
In recent years, many researchers have investigated the association between air pollution and children. However, there has been little research to provide a macroscopic overview in this field. The aim of this study is to characterize the scientific production around the world in this area and map the trends. The relevant literature was searched from 1999 to 2018. To guarantee the quality of the literature, we combined the PubMed and WoS databases. The built-in statistics tools of the Web of Science website were used to display the trend of articles published by year and the distribution of journals. By CiteSpace (5.5.R2), the reference co-citation and burst keywords were extracted. In total, 15,999 target English documents were obtained. We summarized the characteristics of published documents, of research institutes' cooperation, and of the contents. As part of a research hotspot, ten clusters are presented, four popular topics are elaborated. Twenty-four burst words were obtained and analyzed. China has received more attention in recent years. Researchers in this field could carry out more cohorts' studies and fine particulate matter is one good air pollution index. Household air pollution exposure and children's lung function should be paid more attention.

Abstract
INTRODUCTION Cardiopulmonary resuscitation (CPR) guidelines have been updated every 5 years since 2000. Significant changes have been made in each update, and every time a guideline is changed, the instructors of each country that ratify the American Heart Association (AHA) must review the contents of the revised guideline to understand the changes made in the concept of CPR. The purpose of this study was to use a computerized data mining method to identify and characterize the changes in the key concepts of the AHA-Basic Life Support (BLS) updates between 2000 and 2015. METHODS We analyzed the guidelines of the AHA-BLS provider manual of 2000, 2005, 2010, and 2015 using a computerized data mining method and attempted to identify the changes in keywords along with changes in the guideline. RESULTS In particular, the 2000 guideline has focused on the detailed BLS technique of an individual health care provider, whereas the 2005 and 2010 guidelines have focused on changing the ratio of chest compressions and breathing and changing the BLS sequence, respectively. In the most recent 2015 guideline, the CPR team was the central topic. We observed that as the guidelines were updated over the years, keywords related to CPR and automated external defibrillators (AED) associated with co-occurrence network continued to appear. CONCLUSIONS Analysis revealed that keywords related to CPR and AED associated with the co-occurrence network continued to appear. We believe that the results of this study will ultimately contribute to optimizing AHA's educational strategies for health care providers.

Abstract
Tissue engineered (or bioengineered) tracheas are alternative options under investigation when the resection with end-to-end anastomosis cannot be performed. One approach to develop bioengineered tracheas is a complex process that involves the use of decellularized tissue scaffolds, followed by recellularization in custom-made tracheal bioreactors. Tracheas withstand pressure variations and their biomechanics are of great importance so that they do not collapse during respiration, although there has been no preferred method of mechanical assay of tracheas among several laboratories over the years. These methods have been performed in segments or whole tracheas and in different species of mammals. This article aims to present some methods used by different research laboratories to evaluate the mechanics of tracheal grafts and presents the importance of the tracheal biomechanics in both macro and micro scales. If bioengineered tracheas become a reality in hospitals in the next few years, the standardization of biomechanical parameters will be necessary for greater consistency of results before transplantations.
